7. About Huawei 2.0+ advantage, Which description is correct? (Multiple choice)

data on the hard disk storage pools automatically load balancing, avoiding hard disk uneven cold and heat, thus reducing the failure rate of storage system as a whole

overcome the target disk (hot standby) performance bottlenecks of traditional RAID reconstruction , making the reconstructed data stream write bandwidth is no longer a bottleneck of reconstructed speed, thereby greatly enhancing the reconstruction speed and reduces the double disk failure probability, enhance the reliability of the storage system

There is no writing punishment in RAID2.0+ , overcome the impact of writing punishment to LUN writing performance of RAID5 and RAID6 level in the traditional RAID technology ,lead to a single LUN performance improved dramatically.

data on a single LUN distributed to many different hard disk, to avoid the hard disk hotspot, lead to a single LUN performance and capacity has been increased dramatically.
